During these summer months, Middlesex County is facing an unprecedented amount of Giant Hogweed on recreational trails. Giant hogweed is a tall plant that grows up to an astonishing five metres high. Small whisker-like hairs and reddish-purple spots cover its stem. From June to August, it produces a white flower that resembles an umbrella and can stretch one metre wide.
It is important to stay cautious of this plant if you are outdoors recreationally or working. Various parts of the giant hogweed plant (including stems and leaves) release a clear watery sap that is extremely toxic.
Giant hogweed is very poisonous:
- Skin contact with the sap in the presence of UV light (such as sunlight) can cause swelling, itching, and blistering that lasts for months. Some people then become sensitive to UV light and experience a skin-color change that can last for years.
- If the sap gets into your eyes, it can cause permanent blindness.
What do I do if I'm exposed?
- Wash the affected area immediately with soap and water.
- Stay out of sunlight and cover up exposed areas.
- Get medical attention immediately.
